Re: Experimental javascript port of GP

This is great! I notice it doesn't work (at least for me) in Chrome, though I tested that it works in Firefox and Edge. (Any Safari/IE/Opera/etc. users want to chime in?)

I actually attempted this not long ago, though I got stuck toward the end of the process with dependencies. My goal was to get gp2c working, both for its intended purpose and with -G as a code cleanup tool. Any chance of getting this working?

You can try it at

One test is

you can time it using
